Choose the correct answer from the options given below:

(1) A-I, B-IV, C-III, D-II

(2) A-IV, B-I, C-II, D-III

(3) А-III, В-1, C-II, D-IV

(4) A-II, B-IV, C-III, D-I

Answer 1

Correct option is (2) A-IV, B-I, C-II, D-III

(1) In some shallow south American lakes, visiting flamingoes and resident fishes compete for their common food i.e., their is interspecific competition.

(2) The Abingdon tortoise in Galapagos Islands become extinct within a decade after goats were introduced on the island, apparently due to the greater browsing efficiency of the goats this is an example of interference competition.

(3) The larger and competitively superior barnacle Balanus dominates the intertidal areas and excludes the smaller barnacle Chathamalus from that zone.

(4) If two species compete for the same resource, they could avoid competition by choosing for example related species of warblers living on the same tree were able to avoid competition and coexist due to behavioural difference in their foraging activities.
